91 Caprice rear end carrier

[don86T]

Will the 8-1/2 “ carrier from a 91 to 95 Caprice work in the GN rear? I think they are 30- spline so the axles will need to be changed. The Caprice has ABS sensor on the pinion, but I wonder if the carrier is the same.

Thanks,
Don

They interchange.

If you plan on replacing the carrier bearings then get them for the '88 and newer. The OD of the outer race is the same but the bearing size and ID of the inner race are different.

Moser has 30 spline axles readily available for our cars.

Thanks, that is what I was hoping to hear. I found a G80 coded caprice, as long as it's a limited slip and not a locker I'll pull it.

can you change just the spiders & axles

I'm not sure of the earlier cars, but the '96s use an Auburn limited slip. It's non-rebuildable and usally worn out by 50 -75 K miles.

not rebuildable? why not?

Found 2 and both were auburns.

I believe the Auburn uses "cone" style side gears that dig into the case and after time they get dug in too far into the case and they're done. You need to find a "clutch" type differential. When you look at the diff from either side there will be a hole you can see what looks like friction plates used inside an automatic transmission. Also I believe the clutch style uses a piece of spring steel shaped like an S to put preload on the side gears while the cone type uses a pair of side plates that house 5 small coil springs
